OBJECTIVE: To evaluate the usefulness of Positron Emission Tomography with 18F-Fluordeoxyglucose (FDG-PET) to detect tumor recurrence on the basis of tumor marker increases, where negative results have been obtained with conventional methods (TC,RM,MN). MATERIAL AND METHODS: Whole-body FDG-PET was performed on 72 cancer patients: 23 with breast cancer, 18 colorectal cancer, 15 thyroid cancer, 6 lung cancer, 3 ovarian neoplasms and 7 other tumors. In all tumors, tumor recurrence was suspected on the basis of marker increases, and negative results had been obtained with conventional studies. RESULTS: FDG-PET detected lesions in 85% of the patients, which were confirmed in 33%. In 40% of all cases, therapeutic treatments were applied, and in 14% curative surgery was perfomed. CONCLUSION: Whole-body PET-FDG is a useful procedure in the diagnosis of recurring tumoral disease in patients with rising tumor marker levels, where negative results had been obtained with convencional methods.
